Abstract
Continuous veno-venous hemodialysis using high cutoff filters (HCO-CVVHD) is a promising technique, which may be effective to decrease the extremely high level of circulating myoglobin in patients with rhabdomyolysis (RM). Here, we report a patient with RM caused by heat stroke who was successfully treated by HCO-CVVHD. A male patient received HCO-CVVHD with 4 L/h dialysate for 5 days and then pre-dilution continuous veno-venous hemofiltration (CVVH) at a dose of 4 L/h until recovery of renal function. The clearance of myoglobin and albumin at 5 minutes, and at 4, 12, and 24 hours were calculated. The serum myoglobin level decreased from a peak of 25,400 ng/mL on admission to 133 ng/mL at discharge. During HCO-CVVHD, the mean clearances of serum myoglobin at four timepoints were 61.3 (range, 61.0-61.6), 52.3 (38.9-65.8), 47.3 (46.8-47.9), and 43.7 (39.5-48.0) mL/min, respectively, and the mean clearances of albumin were 12.4 (range, 11.8-13.1), 3.1 (2.5-3.8), 1.2 (1.0-1.4), and 0.8 (0.6-1.0) mL/min, respectively. During CVVH, the clearance rates of myoglobin at 5 minutes and 24 hours were 17.0 and 3.8 mL/min, respectively, with a negligible clearance of albumin. HCO-CVVHD can effectively decrease serum myoglobin in patients with RM because of much higher clearance of myoglobin than CVVH. However, attention should be paid to albumin loss during HCO-CVVHD.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
